I am in the process of writing one and will submit it for publishing in about 2 weeks time. Thanks for your thoughts!

I have a BIG dilemma. I am a final year pharmacy student currently finishing off my thesis. Basically, I devised a methodology that is unique in my country and my study was the first of its kind here. Now, there is a 3rd year student who has an extremely similar title to mine, her thesis is basically a follow up of mine. She has asked me for help and basically wants me to explain the methodology to her. Now I am a VERY altruistic person but I feel it is unfair that I have devised a method and that she can just find it ready. I am willing to help her, all I want in return is recognition in any written material she publishes, both her main thesis and any articles she might publish after. How can I ensure that this happens? Would having her sign a form of disclaimer be legally binding or is that too far fetched?

Please help as this is making me really anxious.

Thanks in advance,
